Tsuga heterophylla

Non-toxic to cats

No — western hemlock is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Tsuga heterophylla (Western Hemlock, the conifer) is not listed as toxic by the ASPCA. Like Tsuga canadensis, it must not be confused with Conium maculatum (Poison Hemlock, a highly toxic herbaceous plant). The conifer genus Tsuga poses no known toxic risk to dogs or cats.
